"It turns out to be related" Biological Diversity PPT Courseware 2

We know that many creatures have special morphological structures. The humps of camels, the wings of birds, the leaves of cactus degenerating into thorns... These special structures make the living world more colorful.

Duckweed: The root system is degraded, with only one thin root;

Grass and corn: both have huge root systems.

Collect some plants living in water and some plants living on land, and observe and compare the differences in their roots.

Observe land plants living in different places and compare their leaves. What are the differences?

Banana tree leaves are wide, which is more conducive to evaporating water in the body and regulating the temperature of the plant body.

What other special morphological structures can we tell about plants?

Why do they have these different morphological structures?

The shape of plant leaves is adapted to the living environment.

The morphological structures of plants and animals adapt them to their living environment.

What are the characteristics of the biological organs in the observation picture? What are their respective functions and what kind of environment are suitable for these organisms to live in?

It is easy to grasp tree trunks, suitable for living in the forest, and is helpful for catching small animals.

It can be used for paddling and adapted to living in the water.

They have fleshy pads and make less noise when running on the ground, making them less likely to be spotted by predators.
