Genetic drift happens by chance and can make an allele disappear completely from a gene pool, even if it was a desirable trait that should have been passed down to offspring. The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population.
1. The Cell Wall.
Plants have a cell wall in order to maintain rigidity and stability. Animal cells do not have a cell wall because they have a different structure, which makes them more flexible and able to move around easier.
2. Chloroplasts
Since plants cannot move, they get their energy from the sun. This energy is made inside of the chloroplasts. Animal cells don't have chloroplasts because their energy comes from other organisms.
3. Central Vacuole
The central vacuole provides structure and holds materials and wastes, and also decomposes those wastes. Animal cells don't have a central vacuole because they have lysosomes and normal vacuoles that do the same function.
Answer:
C
Explanation:
A Niche is the role an organism plays in its environment.
Answer: Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
