=> Ribosome --- Produces proteins

=> Cytoskeleton --- Internal support system for cell

=> Golgi body --- Packages proteins into vesicles

=> Endoplasmic reticulum --- Transport system inside cell

=> Nucleus --- Control centre of cell

=> Flagellum --- Long tail-like structure for cell locomotion

=> Mitochondria --- Produces ATP {Powerhouse of the cell}

=> Chloroplast --- site of photosynthesis

=> Amyloplast --- Stores starch in plant cell

=> Centriole --- Produces spindle fibres for mitosis

=> Protoplasm --- Supports all cell organelles

=> Cell membrane --- Semi permeable to control entry and exit of materials.

Answer 2

They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
