Where do male and female gametophytes develop in gymnosperms?

1 answer:

8 0

Gynmosperms are a group of seed producing plants, where the seed are grown on either the leaves (such as a ginko), or scales (such as a pinecone), and gametophytes are found in the same place as seeds, just in a different phase (2 ametes come together to make a seed)

Answer:

<u>With increase of deer, there will be a decrease of producers.</u>

Explanation:

Increasing of deer populations means decreasing of producers. As more and more deers are eating plants, the producer population will decrease. Thus, the producer population are in demand and deers will eventually need to fight for food with other deers–– this is known as competition, which is a biotic factor. An abiotic factor can be lack of oxygen once the producer population has been decreased due to the increase deer population.

Match the call structure with the best description. Each cell structure matches with exactly one description.

Makovka662 [10]

Answer:

Please find the cell structure with their best descriptions below

Explanation:

1. Capsule: Capsules are one of the Glycocalyx that firmly attaches to the cell surface and helps the cell avoid phagocytosis.

2. Slime layer: Slime layer is the other Glycocalyx that is loosely attached to the cell surface and helps the cell prevent dessication.

3. Flagella: The flagella is a long whip-like cell structure found in bacteria and some protists and principally used for moving.

4. Conjugation pilus: Conjugation pilus is a cell structure in bacteria that is used to transfer DNA to another bacteria cell.

5. Fimbriae: Fimbriae is a short, bristle-like protein that project from cell surface and help cells attach to surfaces of other cells.

6. Cell wall: Cell wall is a cellular structure found in plant cell and bacteria cells, whose function is to protect cells from harsh conditions and helps maintain cell shape.

7. Cell membrane: The cell membrane controls passage of substances into and out of the cell.

8. Cytoplasm: The cytoplasm is a gelatinous material found inside the cell.

9. Inclusions: Inclusions are structures in cells that formed from the deposits of nutrients.

10. Endospores: Endospores are structures that protect bacterial genome in a dormant state under adverse environmental condition.

11. Ribosomes: Ribosomes are organelles in a cell that makes polypeptide (protein).

12. Mycolic acid: Mycolic acid is a waxy molecule (long fatty acid chain) that is found in some gram positive bacteria and associated with their cell wall.

13. Nucleoid: A nucleoid is a region in prokaryotic cell where chromosomal DNA and DNA-associated proteins are concentrated.

14. Pili: Pili is similar to the Fimbriae but longer and contain less numerous protein appendages than fimbriae used in attachment.
