All 6 cards in this deck

How does growth occur in animals?

By cell division (mitosis) and differentiation.

What are the three processes by which plants grow?

Cell division, cell elongation and differentiation.

What is cell elongation?

When a plant cell gets longer, increasing the size of the plant.

Give two methods, other than measuring change in length, that show the growth of seedlings.

Measure the change in mass; look at the number/size of leaves (or the width of the seedling).

True or false? In animals, cell division happens all over the body, but in plants it is mainly limited to the meristems.

True. Plant cell division occurs in meristems at the tips of roots and shoots.
