Question

Cells are the basic building blocks of life, and without them, living things would not exist. Millions and billions of cells are joined together to make all living things, both plants and animals. Nearly all cells are very, very tiny and cannot be seen without using a powerful microscope. Cells have different shapes, colors, designs, and functions.
Plant and animal cells have more common parts than parts that are different. Each of the parts has a special function, but the shape, size, and location of the cell parts may vary. Common parts include the nucleus, which is a sphere-shaped body surrounded by a membrane and contains mostly DNA and protein in chromosomes (genetic information). It also controls many functions of the cell and might be called the command center. It regulates various processes in the cell and is in the center of animal cells but on the edge of plant cells.
Next common part is cytoplasm, a jelly-like fluid which fills the cell in which the organelles are suspended. It is located outside the cell nucleus and where most chemical processes take place. The cytoplasm is controlled by enzymes. The cell membrane controls the movement of substances into and out of the cell, as some substances are permitted to pass through, while others are blocked. Other common parts of plant and animal cells include mitochondria, ribosomes, and vacuoles.

a) Where are chromosomes located in a cell?
b) What are they composed of?

Answer 1

Answer:

a) chromosomes are thread like structure which present in nucleas in both animals and plant cell

b) chromosome are composed of protein and dna and genetic information etc...

Answer 2

Answer:

Explanation:

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
