Self-study guidance

1. How many organisms that belong to fungi can you name?

2. What are the differences in shape and color between Penicillium and Aspergillus? What do they have in common?

3. What is the nutritional mode of fungi? (Tip: Depending on whether they can produce their own organic matter, they are divided into autotrophic and heterotrophic types)

4. How do fungi reproduce?

Observe and think

What are the differences in morphology and color between Penicillium and Aspergillus? What do they have in common?

Differences: Penicillium is _______ in color, and the hyphae with spores look _______;

Aspergillus is __________ in color and the hyphae with spores look _______.

Common points: 1. _______ fungi, the bacterial body is composed of _______, and they can all produce _______;

2. Each cell has a cell wall, cell membrane, cytoplasm, _______ and other structures.

Summarize:

Same point

1. The morphological structure of mold is multicellular, and the body is composed of hyphae.

2. Every cell has a cell wall, cell membrane, cytoplasm and nucleus

difference

Penicillium {color green

{Shape broom-like

Aspergillus {color black, yellow, green

{Shape radial

2. Main characteristics of fungi

(1) There is a real nucleus in the cell

(2) Ability to produce spores to reproduce offspring,

(3) There are no chloroplasts in the body, and the nutritional method is heterotrophic.

(4) Suitable for living in warm, humid and organic-rich environments

Classroom testing

1. After the oranges rot, some green mold appears, and some broom-shaped spores can be seen under the microscope. This mold is: ( )

A. Aspergillus B. Penicillium C. Yeast D. Mucor

2. The main characteristics of Penicillium that distinguish it from Aspergillus are ( )

A. Nutritional methods are all heterotrophic B. Spore reproduction

C. The top of the upright hyphae is broom-shaped

D. The top of the upright hyphae is radial

3. In summer, damp clothes and food are prone to mold and hair growth. This is because ( )

A. Bacteria multiply rapidly in warm and humid environments

B. Mold spores germinate into mold on clothes and food

C. Yeast spores germinate when conditions are suitable

D. Bacteria grow under suitable conditions

4. True or False Questions

(1) Penicillium and Aspergillus exhibit different colors, both of which are the colors of spores. ( )

(2) The thalli of Penicillium, Aspergillus and Mushrooms are composed of many hyphae. ( )
