Cells And Cell Theory Quiz

There are prokaryotic (means does not have a true nucleus) and eukaryotic (means does have a true nucleus) cells. There are some cells do not have a true nucleus. But all cells can only come from other cells.

There are no microbodies, Golgi bodies modify and transport proteins, and the nucleus directs the cell by telling it what to do. Cell walls support the plant cell by giving a rigid shape of a rectangle. The cell wall also helps the plant hold on to the water that it has stored.

The brain and spinal cord are seperate organs but they are working together to perform this job.

The nucleus has the DNA (hereditary info), the cytoplasm is the fluid that the organelles of the cell float in, the centrioles aide in mitosis, and the lysosomes break down materials in the cell.

The mitochondrion has two membranes and is kidney-bean shaped. It is the site of cellular respiration because it is where sugars are broken down into energy. Cellular respiration is the process where the cell is provided energy.

The definition of respiration is breaking down chemcials to provide energy for the cell

The different tissues are working together to perfom one job.

Active and passive transport involves materials entering and leaving the cell. But, active requires energy and passive does not. Exocytosis means things leave the cell only. Endocyotosis means things enter the cell only.

In mitosis you end up with 2 daughter cells that are exact copies of the parent cell. In mitosis, you end up with 4 daughter cells that have half of the genetic material and this is where you see genetic variation. There is not way to end up with 2 cells with half of the material.

Chloroplast is part of the plant cell, stomach is an organ, human is an organism but bicep is tissue because it is made up of the same type of cells doing the same job.

Since the question asked about active you are looking for an answer the describes using energy. Answers a, b, d all refer to passive transport which does not require energy

Carbon monoxide is harmful gas that comes out of our car's tail pipe, and chlorophyll is the green pigment that makes plants be green. Glucose and oxygen are produced in photosynthesis so that the glucose can be converted to energy for the cell.

Cells make up tissues. Tissues make up organs. Organs make up organ systems. Organ systems make up organisms.

Oral groove is for eating, eyespot is for sensing light and flagellum is for movement. Lysosomes break down wastes and other materials in a cell that are unwanted.

Order is : cells, tissues, organs, organ systems, organism

Plant cells have structures that the animal cell does not, cells don't really create a product, and all living organims have cells. But all cells function in the same way in that they respire, take in nutrients, respond to stimuli, reproduce and so on.

contractile vacuole gets rid of excess water, flagellum is for movements and chloroplasts are site of photosynthesis in plant cells. The eyespot detects light and helps the Euglena to know where to find light so that it can photosynthesize.

Amoebas move slowly using their pseudopods to anchor them and then the ooze their cytoplasm in the direction of the pseudopod to pull them in that direction.

Paramecium have an oral groove to use to eat.

Euglena reproduce asexually (mitosis), Paramecium can reproduce sexually and asexually. amoebas reproduce asexually
