Description

"The Stems Grow Taller" Plant Growth Changes PPT Courseware 4

plant roots and leaves

Plant roots:

It holds plants in place and absorbs water and minerals from the soil.

Plant leaves:

Can carry out photosynthesis to produce nutrients needed for plant growth and development.

Find a way to demonstrate how water is transported.

Experimental Materials:

A piece of fresh celery and a beaker with red water

experiment procedure:

1.Put the celery into the beaker;

2. Observe the changes in celery;

3. Cut the celery crosswise and observe its cross section.

Experimental phenomena:

Small red spots appear on the cross-section of celery.

Experimental results:

The stems of plants transport water absorbed by the roots from the bottom up.

The role of plant stems

support plants

Transport water and nutrients

How is it transported?

Transport water and minerals absorbed by the roots to all parts of the plant from the bottom up; transport nutrients produced by the green leaves to all parts of the plant from the top down.

Operation:

The ( ) of plants can absorb water and minerals, and can also fix plants in the soil. The ( ) of plants can produce the nutrients needed for plant growth. The ( ) of plants has the function of supporting the plant body and transporting water and nutrients. The stems of plants can transport ( ) and ( ) absorbed by the roots to all parts of the plant from bottom to top; they can transport ( ) produced by green leaves to all parts of the plant from top to bottom.
