Green Plant Cells


What are the organelles found in the cells?
Cell Membrane, Cytoplasm, Nucleus, Nuclear membrane, Endoplasmic Reticulum Ribosomes, Golgi Bodies, Mitochondria, Lysosomes Vacuoles, Cell Wall, Chloroplasts.





List the structural features of
the cells.

Plant cells are easier to identify because they have a protective structure called a cell wall made of cellulose. Plants have the wall; anim

als do not. Plants also have organelles like the chloroplast (the things that make them green) or large water-filled vacuoles.



What are the functions of these organelles?

Cell Membrane- forms the outer boundary of the cell and allows only certain materials to move into or out of the cell
Cytoplasm - a gel-like material inside the cell; it contains water and nutrients for the cell
Nucleus - directs the activity of a cell; it contains chromosomes with the DNA
Nuclear Membrane - separates the nucleus from the cytoplasm
Endoplasmic Reticulum - moves materials around in the cell
Ribosomes - make protein for the cell
Golgi Bodies - are used for packaging and secreting of energy
Mitochondria - break down food and release energy to the cell
Lysosomes - are chemicals used to digest waste
Vacuoles - are storage areas for the cell

Some organelles are found only in Plant cells. These organelles are:

Cell Wall - provides structure to the plant cell

Chloroplasts - contain chlorophyll that is make food for the plant cell

Why are these functions of the organelles important to the living cells?

Each of the organelles of a plant cell has specific functions. without which the cell cannot operate properly.

I learnt that ribosomes makes protein for the cell.

I certainly didn't know that nucleus(es) have a protective layer around it. Hmm...

I found out that the cells contain this substance called Endoplasmic Reticulum which moves substances around

I learnt that nucleus have a protective layer and ribosomes makes protein for cells.

THE CELLS MUST HAVE ALL THE IMPORTANT ORGANELLS TO FUNCTION PROPERLY

Interesting.

I didn't know that there were so many parts inside a plant cell. Hmmm, very interesting.

I learnt that cells have many parts, each is vital to the cell.
