It's diffusion because it's movement from high to low concentration
Cell organelles in Eukaryotic cell:
<span> Eukaryotic cell has many cell organelles which are bounded by double membrane, a single membrane or having with out bounded membrane. I will enlist only four according to question requirement.
</span>
1. Chloroplast:
It is s double membrane bound organelle present only in plant cells. It contain a green pigment called chlorophyll.
Function:
Chloroplast is the site where photosynthesis occurs in the presence of sunlight and glucose is prepared
2. Mitochondria:
It is found in all eukaryotic cells. It iis a double membrane bound organelle.
Function:
Mitochondria is known as power house of cell. It is the site where cellular respiration occurs and ATP is produced by breakdown of glucose in the presence of oxygen.
3. Endoplasmic reticulum:
It is a network of channels extended through out the cell, connecting nuclear membrane with plasma membrane. endoplasmic reticulum having ribosomes attached are called rough endoplsmic reticulum. While some endoplamic reticulum are free of ribosomes these are smooth endoplasmic reticulum.
Function:
a. It is the site where protein synthesis occurs, smooth endoplasmic reticulum is involved in lipid metabolism.
b. It also detoxify the effect of harmful substances.
c. It also help in nerve impulse transmission.
4. Nucleus:
It is one of the most important cell organelle present in the center in animal cell while at one side in plant cell due to the presence of large vacuole. It contains chromosomes.
Function:
Nucleus control all activities of a cell. It contains DNA that acts as a hereditary materials, transfer characters from parents to offspring.
Answer:
hi there!
Explanation:
• Variation light and variation in temperatura
For me these are the problem, because they had to move some plant to the outdoors, because they don´t have enough space inside. So this changed of place could affect the plants.
Answer:
3.1.1 = G
3.1.2 = C
3.1.3 = F
3.1.4 = I
3.1.5 = H
3.1.6 = A
3.1.7 = N
3.1.8 = E
3.1.9 = B
3.1.10 = M
Explanation:
- 3.1.1
Cytokinesis is the process whereby the cytoplasm of a cell divides into two in order to accommodate the already divided nucleus.
- 3.1.2
Cancer is a medical condition that means an uncontrolled division or growth of cells.
- 3.1.3
Metaphase is a stage of mitosis where chromatids line up at the equator of the cell i.e cell plate.
- 3.1.4
Centromere is a point where sister chromatids i.e. replicated chromosomes are joined before separation in the anaphase stage.
- 3.1.5
Tumour is the term given to a mass of cancerous cells. Cells repeatedly divide without control to form a mass called tumour.
- 3.1.6
Carcinoma is a type of skin cancer or rather a cancer that begins in the skin.
- 3.1.7
The cell cycle involves the interphase and mitotic phase. Interphase stage is the stage where the cell grows, multiplies its genetic material and generally prepare while mitosis is the nuclear division.
- 3.1.8
Carcinogens are biological or chemical substances that causes cancers. They are said to be factors that induce cancer.
- 3.1.9
Benign tumor are mass of cancerous cells that do not spread to other parts.
- 3.1.10
A chromatid is the half part of a replicated chromosome. Together, they are called SISTER CHROMATIDS.
Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
