Apologia Biology Module #4 Study Quiz

1. Extracellular digestion is digestion that takes place __________.

Extracellular digestion refers to the process of breaking down food particles outside of the cell. This occurs in organisms that do not have a digestive system within their cells. Instead, they release digestive enzymes or acids into the surrounding environment to break down the food particles. This allows for the absorption of nutrients into the organism's cells for energy and growth.

2. The easiest way to get ride of slime molds is to have a _______.

Slime molds thrive in moist environments, so having a dry area would make it difficult for them to survive and reproduce. Without the necessary moisture, slime molds would not be able to grow and spread. Therefore, maintaining a dry area would effectively prevent the presence of slime molds.

3. Which structures or characteristics exist for the vast majority of fungi?

Haustoria

Hyphae

Stolons

Septate Hyphae

Caps and Stalks

Hyphae are thread-like structures that are present in the vast majority of fungi. They are responsible for the growth and spread of fungi, as they extend and branch out to form a network. Hyphae can be septate, meaning they have cross-walls called septa that divide the hyphae into compartments, or they can be non-septate, also known as coenocytic, where there are no septa and the hyphae are multinucleated. Hyphae play a crucial role in nutrient absorption and reproduction in fungi.

4. What is the function of a Rhizoid Hyphae?

Absorbs nutrition directly from the cytoplasm

Produces spores

Asexually rproduces to make more filaments

Supperts the fungus and digstiong the food

Rhizoid hyphae support the fungus and aid in the digestion of food. They are responsible for anchoring the fungus to its substrate and absorbing nutrients from it. Additionally, they secrete enzymes that break down complex organic matter into simpler forms that can be absorbed by the fungus. This enables the fungus to obtain the necessary nutrients for its growth and survival.
