Question

1. do multicellular organisms grow?
2. do multicellular organisms develop?

Explanation:

Question 21

Multicellular organisms grow. Growth in them occurs through cell division (increasing cell number) and cell enlargement. For example, a plant grows as its cells divide and expand, and an animal like a human grows from a zygote to an adult via millions of cell divisions and cell growth.

Multicellular organisms develop. Development involves changes in the organism from its early stages (like an embryo) to maturity, including cell differentiation (cells becoming specialized, e.g., stem cells becoming nerve or muscle cells) and the formation of tissues, organs, and organ systems. For instance, a frog develops from a tadpole with gills and a tail to an adult frog with lungs and legs, and a human develops from a fetus with underdeveloped organs to a fully functional adult with complex organ systems.

Answer:

Yes, multicellular organisms do grow.
