What is plant cell ??


Plant cells are a type of eukaryotic cell that are found in the organisms within the Plant Kingdom.

Eukaryotic cells contain a nucleus. Plant cells differ from other eukaryotic cells because the organelles present are different.

                                                What is animal cell ??


An animal cell is a type of cell that dominates most of the tissue cells in animals

Animal cells are different from plantcells because they don't have cell walls and chloroplasts, which are relevant to plant cells.




Hi guys .. its me Aisyah. Welcome to biology life !


What is Biology ?

 The word biology is derived from the greek words /bios/ meaning /life/ and /logos/ meaning /study/ and is defined as the science of life and living organisms.

 

What is cell ???

 The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.

Animal Cell

Plant Cell
Cell wall
Absent
Present (formed of cellulose)
Shape
Round (irregular shape)
Rectangular (fixed shape)
Vacuole
One or more small vacuoles (much smaller than plant cells).
One, large central vacuole taking up 90% of cell volume.
Centrioles
Present in all animal cells
Only present in lower plant forms.
 Chloroplast
Animal cells don't have
chloroplasts.
Plant cells have chloroplasts because they make their own food.
Cytoplasm
