What is the difference between Vegitative cell and Generative cell?
**Difference between Vegetative cell and Generative cell**
Vegetative cells and generative cells are two types of cells found in plants. They have distinct characteristics and functions within the plant reproductive process. Let's explore the differences between these two cell types:
**Vegetative Cell:**
1. **Definition:** A vegetative cell is a specialized cell that is involved in the asexual reproduction and growth of plants.
2. **Location:** Vegetative cells are typically found in the vegetative parts of the plant, such as the leaves, stem, and roots.
3. **Function:** The main function of vegetative cells is to carry out essential metabolic processes, such as photosynthesis, respiration, and storage of nutrients. They are responsible for plant growth, development, and maintenance.
4. **Characteristics:** Vegetative cells are usually larger in size compared to generative cells. They have a well-developed cytoplasm, prominent nucleus, and various organelles like chloroplasts, mitochondria, and vacuoles.
5. **Reproduction:** Vegetative cells can undergo mitosis to produce identical daughter cells, allowing for asexual reproduction in plants. They can give rise to new individuals through processes like budding, fragmentation, or regeneration.
**Generative Cell:**
1. **Definition:** A generative cell is a specialized cell that is involved in the sexual reproduction of plants. It is part of the male reproductive system of flowering plants.
2. **Location:** Generative cells are typically found within the pollen grain, which is produced in the anther of the flower.
3. **Function:** The main function of generative cells is to participate in the process of double fertilization during plant reproduction. They are responsible for the formation of male gametes or sperm cells.
4. **Characteristics:** Generative cells are relatively small in size compared to vegetative cells. They have a condensed cytoplasm and a distinct nucleus. They lack chloroplasts and other typical plant cell organelles.
5. **Reproduction:** Generative cells are involved in the formation of male gametes. During double fertilization, one generative cell divides to form two sperm cells. These sperm cells are released from the pollen tube and fertilize the egg cell and the central cell of the female reproductive system.
In conclusion, vegetative cells are involved in asexual reproduction and growth of plants, while generative cells play a crucial role in the sexual reproduction of flowering plants. Vegetative cells are larger and found in vegetative plant parts, while generative cells are smaller and located within pollen grains.
What is the difference between Vegitative cell and Generative cell?
Cellular differentiation of a generative and a vegetative cell during pollen development is requisite for sexual plant reproduction and is initiated by an unequal(asymmetric)cell division. The smaller, generative cell produces two sperm cells, or male gametes, whereas the larger, vegetative cell produces an elongated pollen tube, agametophytic cell, to deliver the male gametes to the embryo sac. The distinct differences between two kinds of cell are found in organelle composition and cytoskeletal organization in their cytoplasm. Recent transcriptome analysis also revealed the difference in gene expression profiles between both cells. We pay attention to the difference of theirchromatin configuration, that is assumed to be associated with the difference in gene activity between the two types of nucleus. Namely, the generative nucleus has highly condensed chromatin, as do the nuclei of animal sperm, whereas the vegetative nucleus contains diffuse chromatin. For this reason, by developing an efficient method to isolate the generative and vegetative nuclei from lily pollen protoplasts, their histone composition was investigated biochemically and immunocytochemically.
