how are plant cells and human cells the same?
a. they can produce their own oxygen.
b. they make their own food from sunlight.
c. they can receive nutrients through the cell wall.
d. they use mitochondria to release energy from sugars.

Answers

A. They can produce their own oxygen

Plant cells and human cells are similar in the sense that they both use mitochondria to release energy from sugars.

Plant cells and human cells are two distinct kind of cells. Plant cells are autotrophic meaning that they can synthesize their own food using energy from sunlight but human cells are heterotrophic meaning that they depend on other organisms for food.

Despite this huge difference between plant and human cells, they still possess some similarities. One major similarity between plant and animal cells is that they both possess MITOCHONDRIA and use it to undergo cellular respiration.

Cellular respiration is a process that breaks down organic substances like sugars to synthesize ENERGY (ATP). This process occurs in the MITOCHONDRIA of both plant and animal cells.

Therefore, the fact that both plant and human cells use mitochondria to obtain energy is a similarity between them.

Which phase of mitosis is shown in the diagram?
O anaphase
O metaphase
O telophase
O prophase

Answers

The phase of mitosis in the diagram is Anaphase.

The cell cycle can be divided into interphase and mitotic M phase.

The mitotic M phase refers to the process cell division of somatic cells.

This phase (M phase) can be divided into a series of sequential steps that include Prophase, Metaphase, Anaphase, Telophase and Cytokinesis.

In Anaphase, the chromosomes separate and travel to opposite poles of the cell.

In conclusion, the phase of mitosis in the diagram is Anaphase.
