it is enclosed in a membrane. The organelle's job is to process proteins that were synthesized in the endoplasmic reticulum and distribute them to other parts of the cell, or prepare them to be exported outside the
One example is the mitochondrion— commonly known as the cell's "power plant" — which is the organelle that holds and maintains the machinery involved in energy-producing chemical reactions (Figure 3). Figure 2: The composition of a bacterial cell Most of a cell is water (70%). The ...
1. What is the cell membrane? 2. What does it contain? How does it function? 3. Is it prokaryotes or eukaryotes? Which organelle is not found in an animal cell? (a) nucleus (b) cell wall (c) cell membrane (d) mitochondria. ...
What is the difference between anaerobic and aerobic respiration? What is the difference between aerobic and anaerobic respiration? What are anaerobic fermentation products? In which organelle of the cell does the anaerobic type of respiration occur?
A vacuole is an organelle that is found in many types of cells, including animal, plant, fungi, bacteria, and protist cells.The main vacuole function is to store substances,typically either waste or harmful substances, or useful substances the cell will need later on. ...
I guess that begs the question about why leaves turn different colors in the fall. Do the leaves get overwhelmed by some other organelle in the cells that has a different color? How many grana does a chloroplast usually have? Is there just one big one or a lot of smaller ones?
which is physically similar to the cell's plasma membrane. The nuclear envelope contains nuclear pores that allow for the influx and egress of certain molecules. This organelle is the largest in any cell, accounting for as much as 10 percent of a cell's volume, and is readily visible using...
Plants are the most common types of autotrophs, and they use photosynthesis to produce their own food. Plants have a specialized organelle within their cells, called achloroplast, which allows them to produce nutrients from light. In combination with water and carbon dioxide, these organelles prod...
Most of the organelles within an animal cell are also surrounded by their own membranes. Nucleus The nucleus is a big organelle. It controls the activities of the cell. The nucleus contains chemical instructions in the form ofDNA. DNA Strands ...
Discovery of Cells First cells were discovered by Robert Hooke –Looked at cork cells –No organelles were visible Van Leeuwenhoek looked a living cellular life in pond water –“EEWW this is in the water we drink” Advancement in microscopes lead to the visualization of organelles ...
