Explanation:

Plant cells: (1,3,5,6)

Plant cells differ from animal cells in several ways.

Cell wall: One of the most defining one is plant cells have cell walls. These cell walls are rigid and they cover the plasma membrane of the plant cell. Cell walls have 3 layers and the outermost one is called the middle lamella, which is the cell cement. It acts like a cement because it is what holds one plant cell and the adjacent cells together. The middle lamella is made up of pectin.

The cell wall also has layers made up of cellulose, which happens to be a macromolecule as is the most abundant of its kind on Earth. They form bundles called microfibrils.

Chlorophyll: Chlorophyll are molecules found in plant cells that play a role in food production in plants. Chlorophyll absorbs sunlight which is used in the process of food making called photosynthesis, along with other elements like water and carbon dioxide. Also chlorophyll gives the green pigmentation of plants.

Chloroplast: Chlorophyll are encased in an organelle called chloroplast. Chloroplasts are where photosynthesis takes place. They are found in the leaves of plants. Because they use chlorophyll, the are also green.

Other parts of a cell: (4, 9,11.15, 16, 17)

Both plant and animal cells also have similar organelles.

Endoplasmic Reticulum (ER): There are two types: smooth endoplasmic reticulum(SER); and rough endoplasmic reticulum(RER). The SER acts like a storage unit for lipids and steroids. They also help in the production as well. RER is a pckaging and synthesis area. It is rough because they have ribosomes on them.

Ribosomes: Ribosomes are small organelles in the cell that are partly made up of rRNA or ribosomal RNA. They play an important role in protein synthesis. They help translate the DNA code that the mRNA transcribed to determine what type of protein will be formed.

Golgi Apparatus: Also known as the golgi complex, is an organelle in the cell that serves as a sorting and packaging area. It collects simple molecules and packages them into more complex molecules which would be stored if the cell would need it, or it will be sent out of the cell. These complex molecules are packed into vesicles. A transition vesicle is made from the protein in the ER is transported to the golgi apparatus, which then processes its contents. It then releases a secretory vesicle, that is then brought to the cell membrane.

Centrioles: Centrioles are small, cylinder-shaped organelles that aid in cell division. They are made up of the protein, tubulin. These centrioles produce spindles or spindle fibers that pull on the chromosomes during cell division and split them up.

A, B and D

Explanation:

i just did the assingment 🙂

B

Explanation:

Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells.

A.The DNA in the parent cell nucleus makes a copy of itself and is then split between the two daughter cells during meiosis.

Explanation:

5. 19thomasar says:

A scientist looks at two different cells under a microscope. Cell A has many more ribosomes than cell B. What can the scientist conclude about the cells?

A. Cell A makes more proteins than cell B. B. Cell B makes more proteins than cell A. C. Cell A and cell B make the same proteins.

this is because ribosomes are responsible for the synthesis, or production, of proteins.

Since the time of Linnaeus, the classification of organisms into kingdom has significantly changed. Fungi have been classified as a separate kingdom (they have been classified under plants before) and the development of microscopy has enabled scientist to study microscopic organisms and classify them into the Protista and Monera kingdoms.

The phylum is one of the highest ranks of classification, right under the rank of kingdom, so it contains a great number of species. For example, the phylum of Arthropoda contains all the insect, spider, crustacean and millipede species.

Before the methods of genetics and molecular biology research were developed, species were classified only based on their physical appearance. But now, we can determine how closely related species are by their genes as well. This solves the problem of species that have developed convergent traits as a response to similar environments, but that, in fact, are not genetically similar.

The classification of viruses has always been a difficult question for scientists. Viruses have their own genetic material enclosed in a protein coat, but they can not reproduce on their own since they need the metabolism and the genetic machinery of other cells to survive.

The two species are definitely members of the Eukarya domain because they have nuclei. All of the other domains, Bacteria, and Archaea lack all organelles including the nuclei. If both of the species produce eggs, they may be members of the animal kingdom.
6. The correct answer is A
Even though both bacteria and archaea are single-celled prokaryotes the differences between them are great. Their cell walls and cell membranes are built from different lipids and the enzymes that have a role in the central dogma differ significantly.

Sexual reproduction in eukaryotes has a purpose of exchanging the genetic material between two individuals. The process of conjugation in bacteria is very similar to sexual reproduction, but there are no specialized sex cells and the cells do not form haploid cells through meiosis.

8. The correct answer is D
Natural selection has filtered the population of bacteria. Only the individuals resistant to the antibiotic have managed to survive and leave offspring, producing a population of bacteria that is solely consisted of antibiotic-resistant individuals.

9. The correct answer is D
Red algae are autotrophic organisms. This means that they are producers of food, in this case, they can produce sugars trough conversion of sunlight in the chloroplasts. The amoeba must consume other organisms or organic particles to survive, and the only way for it to do it is through the process of endocytosis since they lack mouths.

10. The correct answer is B
Molds are fungi that are dependant on moisture. They are not photosynthetic and they lack flagella, so the most efficient way to eradicate molds would be to dry out the area and the lack of moisture will cause the disappearance of the mold.

Explanation:

3 is incorrect because every organism is made of cells, not just unicellular organisms. these organisms do, however, have one cell that carries out all functions for the organism.

5 is incorrect because plants are multicellular organisms and thus have more than one cell.

A. The DNA in the parent cell nucleus makes a copy of itself and is then split between the two daughter cells during meiosis.

Explanation:

During meiosis crossing over also occurs to exchange the genetic material in sister chromatids.
