A plant cell is bounded by a cell wall and the living portion of the cell is within the walls and is divided into two portions: the nucleus, or central control center; and the cytoplasm, a fluid in which membrane bound organelles are found. Between the primary cell walls of adjacent plant cells, lies a pectic middle lamella. There can be a secondary cell wall which would be located just to the inside of the primary wall. Both walls consist mainly of cellulose, but the secondary cell wall may contain lignin and other substances. The outer boundary of the protoplasm (cytoplasm and nucleus) is a sandwich-like, flexible plasma membrane. This membrane regulates what enters and leaves the plant cell. Plant cell organelles include: endoplasmic reticulum, with and without ribosomes attached; Golgi bodies, mitochondria, and plastids. Plastids are chloroplasts, chromoplasts or leucoplasts-depending on the color and likewise the function. Chloroplasts are of specific interest to those studying plants. A plant cell also, obviously, contains a nucleus which is bounded by a nuclear envelope with pores. The pores in the nuclear envelope allow for movement of substances in and out of the nucleus. Within the nucleus is a number of chromosomes. The number present is specific to the organism and it will be later noted how sex cells contain one-half the number of chromosomes, and restore chromosome number upon fertilization. All of these organelles and the nucleus are suspended in the cytoplasm. The cytoplasm has movements that are referred to as cytoplasmic streaming or cyclosis. The particular function of the other organelles contained in plant cells can be reviewed below:
It is necessary to note a bit about the form of chloroplasts, as you will encounter them throughout this tutorial. Inside a chloroplast is a matrix called the stroma. Enzymes are found in the stroma as well as grana-stacks of coin-shaped discs, called thylakoids. It is within the thylakoids that photosynthesis takes place. Note that chloroplasts, like mitochondria contain their own DNA. They do rely on proteins from the nucleus, and are considered semi-autonomous organelles. Photosynthesis will be discussed in greater detail in the Plant Metabolism tutorial.
Plant cells are also notorious for having huge vacuoles. Up to 90% of the volume of a mature cell may be taken up by a single large vacuole or several vacuoles. The vacuole is bound by a special membrane, called the tonoplast, and contains cell sap-which is composed of dissolved substances and may include pigments.
cell wall, the plant cell has a cell wall and a cell membrane the animal cell has only a cell membrane.
The cell wall.
cell wall
A cell wall
a Golgi complex is a not a cell.....it is a cell organelle...that is a small part in the cell...it is present in animal cells
Both, most plant cells have a cell wall but animal cells do not.
The nucleus
Chloroplasts and cellular walls, plus a large central vacuole are parts of plant cells and not animal cells.
Actually, plant cells have all of the cell organelles which animal cells have, only more. Lysosomes, which are most commonly found in animal cells are not often found in plant cells.
Cells are not part of cells, your question makes no sense.

The nucleus is part of both the plant and animal cells.
a Golgi complex is a not a cell.....it is a cell organelle...that is a small part in the cell...it is present in animal cells

Cell wall Chloroplasts
Lysosome ,Centriole, and VesicleActually, animal cells do not have any different organelles than plant cells, other than plant cells having a membrane. animal cells do not have a membrane, they have a cell wall.
on animal cells and plant cells
It is the part that controls both animal and plant cells
They are not so different. I am aware of two major differences: 1. Centrioles are not present in plant cells. Other structures are present to assemble and organise the spindle fibres. 2. At the end of telophase, there is no cleavage of the cytoplasm; Rather the Golgi apparatus pinches off vesicles which deposit to form a new cell wall. This is how cytokinesis takes place in plant cells, in contrast with animal cells where the cytoplasm cleaves.
A vacuole is a part of an animal cell. It contains waste products to be expelled from the cell. [Extra Information: Vacuoles are present in plant cells too. It is the structure that contains water and helps to keep the plant cell rigid.]
Yes they are and they are also apart of plant cells
