Q

Why do organisms grow by increasing the number of cells instead of cell size?

A

Increasing cell size reduces surface area relative to volume, making nutrient exchange inefficient and complicating cellular control.

Q

How do plant and animal cells differ in cytokinesis?

A

Plant cells complete cytokinesis using a cell plate, while animal cells divide by splitting the cytoplasm.

Q

What outcomes should be achieved after completing the lesson on cell division?

A

You should be able to illustrate and explain the process of cell division by mitosis, order pictures of cells in various stages, and list differences and similarities between plant and animal cell division.

Q

What type of organisms reproduce asexually?

A

Most single-celled organisms reproduce asexually.

17
Q

What factors determine the type of reproduction in organisms?

A

The conditions determining which type of reproduction takes place are often environmental.

18
Q

What are some keywords related to asexual reproduction?

A

Asexual Reproduction, Binary Fission, Protists, Amoeba, Fungi, Budding, Sporulation, Regenerate, Vegetative propagation.

19
Q

How do protists reproduce asexually?

A

Protists reproduce using standard mitosis.

20
Q

What is an example of a disease caused by protists?

A

Amoebic dysentery is a disease caused by protists.

21
Q

What are the two ways fungi reproduce asexually?

A

Fungi reproduce by budding and spore formation (sporulation).

22
Q

How do yeast reproduce?

A

Yeast reproduce by budding, where a tiny bud forms on the cell wall and eventually breaks off.

23
Q

What is sporulation?

A

Sporulation is when molds produce spores in a case called a sporangium.

24
Q

How do sponges and hydra reproduce?

A

Sponges and hydra reproduce by budding.

25
What is fragmentation in reproduction?
Fragmentation is when an organism, like a planaria, can create new individuals from cut parts.
26
What is regeneration?
Regeneration is the ability of an animal to regrow a tissue, organ, or part of the body.
27
Which animals have the greatest ability to regenerate?
Animals with the least amount of cell specialization have the greatest ability to regenerate.
28
Can humans regenerate body parts?
Humans can regenerate certain tissues such as blood, bone, and outer skin.
