Answer :

Answer:

Robert Hooke is known for the first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork)

Plants are made of cells, Animals are made of cells, Cells produce other cells.

Eukaryotic have a nucleus meanwhile prokaryotic lacks of it.

Bacteria are prokaryotes

Cholesterol stabilize the cell membrane, less fluid at higher temp and less solid at lower temp.

Chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material

Plant cell have cell wall, chloroplasts, plastids, and a central vacuole

Refers to going from regions of high concentration of some entity to regions of low concentration, and such movement generally occurs spontaneously,

Facilitated diffusion is the diffusion of molecules assisted by transport proteins

Passive transport no needs energy, move molecules trough phospholipid bilayer

Active transport needs energy, move molecules trough membranes

Endocytosis engulf substances and form vesicles (into the cell) (active transport)

Phagocytosis cell eats solid particles or big substances

Pinocytosis is the cell drinking, liquid substances

Exocytosis vesicles move through the plasma membrane, release the contents (outside the cell) (active transport)

Animal and plant cell organelles: nucleus, nuclear membrane, nucleoplasm, nucleolus, cillia, flagella, Rough Endoplasmic Reticulum, Smooth Endoplasmic Reticulum, Golgi apparatus, plasma membrane, vesicles, lysosomes, peroxisomes, centrioles, mitochondria, cytoplasm, cytosol, cytoskeleton, ribosomes, vacuoles, cell wall, chloroplasts.

Another name for a fertilized egg is zygote

Hope it helps :)
