Answer 1

Answer:

a). Organ is a collection of tissues performing specific functions in a human body. On the contrary, organelles are cellular structures performing specific functions within the cell.

b). The cell wall is metabolically inactive The cell membrane is metabolically active.

c). nucleus :Bound by the nuclear envelope

nucleolus :It has no limiting membrane

d). Chloroplast helps in photosynthesis whereas leucoplast helps in storage of fats. D. Chloroplast helps in storage of fats whereas leucoplast helps in photosynthesis. Hint: The plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms.

e). ribosomes :It is evenly distributed in the cytoplasm

lysosomes :It can be found in the cytoplasm either bound to the endoplasmic reticulum or scattered in the cytoplasm.

f). The difference Between Cytoplasm and Protoplasm are almost minimal and both terms are used interchangeably. But for academic purposes, Cytoplasm is all the contents inside the cell membrane excluding the nucleus. And protoplasm includes cytoplasm, plus, the nucleus of the cell.
