Question

State exact location of the following:

i) Endoplasmic reticulum
ii) Adipose tissue
iii) Lenticels
iv) Enamel
v) Melanin​

Answer 1

Answer:

1) Endoplasmic reticulum - The endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells. All eukaryotic cells contain an ER. In animal cells, the ER usually constitutes more than half of the membranous content of the cell.

2) Adipose tissue -Adipose tissue is found in various places in the body. Some of these locations include the subcutaneous layer under the skin; around the heart, kidneys, and nerve tissue; in yellow bone marrow and breast tissue; and within the buttocks, thighs, and abdominal cavity.

3)Lenticels -Lenticels are present on the older stem of plants. The lenticel is a portion of the periderm which is developed through the activity of the phellogen. These are lens-shaped openings in the trunk of woody trees.

4) Enamel - Tooth enamel is a hard substance found in the shell of each of your teeth and is the part of the tooth that's visible when you look in your mouth. Enamel is considered the hardest substance in the human body.

5) Melanin- The melanin in the skin is produced by melanocytes, which are found in the basal layer of the epidermis.
