Transcript of Human Body vs. Plant Cell

A cell is like a human body because it is made out of smaller parts that help it function. The brain of a human body is like the nucleus of a cell
because the brain controls the functions of the body, and
the nucleus controls the functions of the cell. The heart is like the mitochondria in a plant cell
because the heart allows your body to live by pumping
blood throughout the body, and mitochondria create
energy for the cell. The mouth of the body is like the cell membrane
of a cell because your mouth controls what comes
in and goes out of your body, just like the cell
membrane does for the cell. The skin of a body is like the cell wall of
a plant cell because the skin protects your
organs and other inner body parts and the
cell wall protects the inside parts
of a cell. The veins of a human body are like the endoplasmic
reticulum (ER) of a cell because veins carry blood
throughout the body, and the ER carries materials
throughout the cell. The stomach of the body is like the vacuole of the cell
because both store food. The saliva glands in the human body are like the
ribosomes in a cell because they both produce a particular
substance for their larger unit. The pores of the body are like the Golgi body in a cell because the Golgi body receives materials from the endoplasmic reticulum (ER) and sends them outside of the cell, and pores allow certain substances out of your body such as sweat. The intestines in a body act like lysosomes in a cell because
intestines break down food, and lysosomes break down food
and worn out cell particles. Melanin in your skin is like chloroplasts in a plant cell because
chloroplasts take the sun's energy and turn it into food for the cell, and melanin takes the sun's energy and turns it into Vitamin D for the body. The nucleus is located in the cytoplasm of both a plant and animal cell. It acts as the control center or brain of the cell. Nucleus Plant Cell Endoplasmic Reticulum (ER)- ER is located in the cytoplasm next to the nucleus in both a plant and animal cell. It is a network of passageways that carries materials from one part of the cell to another. Vacuole Golgi Body The Golgi body is located in the cytoplasm close to the ER, in both plant and animal cells. The Golgi body receives materials from the ER and sends them outside of the cell. The vacuole is located in the cytoplasm of plant and sometimes animal cells. A plant often has only one large vacuole and an animal cell may have vacuoles, or it may not. It stores food and waste products for the cell. In a plant cell it also regulates the turgor pressure. If the plant has sufficient water, the vacuole expands and makes the plant stiff and rigid. When a plant does not get enough water the vacuole deflates in a way and the plant wilts. Lysosomes- Lysosomes are located in the cytoplasm of both plant and animal cells. Lysosomes break down food and worn out cell particles. Mitochondria- Mitochondria are located in the cytoplasm of both plant and animal cells. They are the "power-houses" of the cell because they convert energy from food particles into energy the cell can use to carry out its functions. Chloroplasts- Chloroplasts are located in the cytoplasm of only plant cells. They use energy from the sun to produce food for the cell. They are essential to photosynthesis. Ribosomes- Ribosomes are located next to or attached to the ER and also throughout the cytoplasm in both plant and animal cells. Ribosomes function as factories to produce proteins. Often they are attached to the ER because then the proteins can be transferred straight through the wall of the ER. Cell Wall- Located on the outermost part of only plant cells. The cell wall acts as the barrier that protects the cell and helps it keep its shape. Cell Membrane- The cell membrane is located on the outside of animal cells and on the inside of the cell wall of plant cells. The cell membrane controls what substances come in and out of the cell. Cytoplasm- Located inside the cell membrane and amongst the organelles of both plant and animal cells. It is the jel-like fluid in which many organelles can be found.
