Ответ:
Fungi doesn't have chlorophyll and they digest food internally so your 2 answers are B and D.
Ответ:
3. They digest food externally.
4. They can absorb nutrients from food, even though they lack digestive enzymes.
Explanation:
Fungi are nutritionally heterotrophic, they may be saprophytes, parasites or some are symbionts.
Most of the fungi are saprophytes and get their nutrition by absorbing organic compounds from the environment.
The hypha of the fungus have high surface-area-to-volume ratios so, they are well adapted to absorb nutrients from their environments.
The fungal hypha release of hydrolytic enzymes in the external medium which breaks down large organic molecules such as carbohydrates proteins and fats into smaller molecules. These simple molecules are then absorbed as nutrients into the fungal hyphae.
Ответ:
a sarcodine because it has a pseudopod
The diagram is showing a sarcodine because it has a pseudopod. Sarcodine is a protozoa. These organisms exhibit cytoplasm and use a temporary extension cytoplasmic extension called as pseudopodium, which helps in locomotion and feeding. The shape of these organisms is typically circular or irregular. They may contain more than one nucleus. The food which adheres to the surface of the cell is trapped by the pseudopodium and is digested by the vacuoles.
