Memory link:

①What structure does human growth and development start from?

②How are the structural levels of animal bodies composed from micro to macro?

③What is an organization?

④What are organs?

Did you answer it correctly?

①What structure does human growth and development start from?

fertilized egg.

②How are the structural levels of animal bodies composed from micro to macro?

Cell → Tissue → Organ → System → Animal body (human body)

③What is an organization?

A group of cells formed by cells with similar shapes, structures, and functions united together is called a tissue.

④What are organs?

Different tissues come together in a certain order to form organs.

Preview outline:

1. How do green flowering plants live?

2. What organs do green flowering plants have, and what are their functions?

3. How do plants form tissues from fertilized eggs? Same as animals?

4. What tissues are organs made of?

5. Is the plant body a whole? Why?

1. Green flowering plants have six major organs

Vegetative organs: roots, stems, leaves

Reproductive organs: flowers, fruits, seeds

Are the organs of plants composed of various tissues like animals?

Inquiry activities

Invite students to divide into groups to conduct research on the real objects.

Detailed anatomy, observation, and comparison with books

P64 Figure 2-18 "Several major tissues of plants" to identify.

Think: What tissues are made of the organ you are observing? What functions do they have?

2. Several tissues of plants

Meristem: cell division

Protective tissue: protective role

Nutritional tissue: stores nutrients

Conveying tissue: transports substances

Consolidate testing:

1. Choice:

1. When eating watermelon, the edible “red” pulp part is actually ( )

A. An epithelial tissue B. A nutritional tissue

C.an organ D.a system

2. Which of the following structures does not belong to an organization ( )

A. Leaf epidermis B. Tomato pulp

C.Peanut seeds D.Apple peel

practise

When you eat sugar cane, you first peel off the tough skin of the sugar cane stem; when you chew the sugar cane stem, there will be a lot of sweet juice; the residue left after chewing is spit out. From the perspective of tissues and organs, let’s talk about what tissues the sugarcane stem is composed of?

The tissues that make up the sugarcane stem include protective tissue, vegetative tissue, conductive tissue, etc.

Where are the protective tissues located in the plant body?

Mainly distributed on the surface of various plant organs.

What tissues run through the roots, stems, and leaves of plants?

Conveying tissue.

If you pinch off the top of a branch, will the branch continue to grow? Why?

cannot.

Because there is meristem tissue at the top of the branch, when the meristem tissue is pinched off, the cells cannot divide and increase in number, and the branch cannot continue to grow upward.
