In Funaria, a moss species, the number of chromosomes in different structures can vary. Let's examine the number of chromosomes in rhizoids, calyptra, theca, and foot.
1. Rhizoids:
Rhizoids are thread-like structures found in mosses that anchor the plant to the substrate. They do not have a direct role in reproduction. In Funaria, the number of chromosomes in rhizoids is given as 20.
2. Calyptra:
Calyptra is a protective cap-like structure that covers the developing sporophyte in certain moss species. It is derived from the archegonium, a female reproductive structure. The number of chromosomes in the calyptra can vary depending on the species. However, in this case, the number has not been provided explicitly. Therefore, we cannot determine the exact number of chromosomes in the calyptra based on the given information.
3. Theca:
Theca is the capsule of the sporophyte in mosses. It contains the spores and is involved in reproduction. The number of chromosomes in the theca is usually double the number present in the gametophyte (the dominant phase in the moss life cycle). In this case, since the number of chromosomes in the rhizoids is given as 20, we can assume that the number of chromosomes in the theca would be double, i.e., 40.
4. Foot:
The foot is the basal region of the sporophyte in mosses. It is responsible for absorbing nutrients from the gametophyte and anchoring the sporophyte. Since the foot is derived from the gametophyte, it would have the same number of chromosomes as the gametophyte. In this case, the number of chromosomes in the foot would also be 20, based on the given information.
Therefore, based on the information provided, the number of chromosomes in Funaria would be:
- Rhizoids: 20 chromosomes
- Calyptra: Unknown (not provided)
- Theca: 40 chromosomes
- Foot: 20 chromosomes
The correct answer choice would be A) 20, 40, 40 respectively (assuming the calyptra has the same number of chromosomes as the rhizoids). However, it is important to note that the number of chromosomes can vary among different species and even within different individuals of the same species.
1. Rhizoids:
Rhizoids are thread-like structures found in mosses that anchor the plant to the substrate. They do not have a direct role in reproduction. In Funaria, the number of chromosomes in rhizoids is given as 20.
2. Calyptra:
Calyptra is a protective cap-like structure that covers the developing sporophyte in certain moss species. It is derived from the archegonium, a female reproductive structure. The number of chromosomes in the calyptra can vary depending on the species. However, in this case, the number has not been provided explicitly. Therefore, we cannot determine the exact number of chromosomes in the calyptra based on the given information.

Theca is the capsule of the sporophyte in mosses. It contains the spores and is involved in reproduction. The number of chromosomes in the theca is usually double the number present in the gametophyte (the dominant phase in the moss life cycle). In this case, since the number of chromosomes in the rhizoids is given as 20, we can assume that the number of chromosomes in the theca would be double, i.e., 40.

Since the foot is derived from the gametophyte, it would have the same number of chromosomes as the gametophyte. In this case, the number of chromosomes in the foot would also be 20, based on the given information.
Therefore, based on the information provided, the number of chromosomes in Funaria would be:
- Rhizoids: 20 chromosomes
- Calyptra: Unknown (not provided)
- Theca: 40 chromosomes
- Foot: 20 chromosomes
The correct answer choice would be A) 20, 40, 40 respectively (assuming the calyptra has the same number of chromosomes as the rhizoids). However, it is important to note that the number of chromosomes can vary among different species and even within different individuals of the same species.
