Difference between animal cells and plants cells​

Answers

Answer:

A plant cell have a vacuole, chloroplasts and A cell wall

Chloroplasts - Contain a green pigment (turns the plant green) To do with photosynthesis.

Cell Wall - Holds the cell up and keeps it in a rigid structure.

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

Which statement is NOT applicable to scientific models?A) Models are a description of nature that can predict things about similar situations.
B) Models are too complex to be used by the average person; so they are limited by who can use them.
C) Models are testable ideas created by the human mind to tell stories about what happens in nature.
D) Models are approximations or a sum of a real system that omits all but most essential variables of a system.

Answers

Answer:

The correct answer will be option-B.

Explanation:

Scientific models are the simplified visual representations of the complex ideas, object or a system.

The scientific models play a central role in the science as they are used in the research based on the predictions to prove or reject the hypothesis as well provides a good medium of explanation of a complex process.

Since the models are very simple representations of the complex process which can be used and understand easily by a layman, therefore, Option-B is the correct answer.

i think its b because it seems the most unreasonable hope i helped :)
