Organelles! Flashcards
Name as many organelles as possible
Cell Wall, Cell membrane, Nucleus, Golgi Body, ER, Mitochondria, Ribosomes, Lysosomes, L AND S Vacuole, Cilia
Purpose of the Cell Membrane
Is a porous organelle that allows different material to pass through and come in. It also provides shape for the cell.
Purpose of Mitochondria
Powerhouse of the cell, the more energy a cell needs, the more mitochondria found.
Purpose of Cytoplasm
Jelly-like fluid that holds all the organelles in together.
Purpose of Nucleus and is it possible to not have a Nucleus
Is the brain of the cell, and inside contains DNA or genetic material which is used in the process of reproducing. Moreover, it controls the cell and organelles job. ! RED BLOOD CELLS DONT HAVE NUCLEUS!
Purpose of the Ribosomes
The ribosomes is the protein and nutrient of the cell, both animal and plant cells contain them. In the plant cell, it works along with photosynthesis to obtain energy.
Purpose of Lysosomes
Lysosomes are the garbage collects of the cell, they have a liquid inside that can break down cell debris.
Purpose of Vacuoles
The vacuoles store different nutrients such as water. The large vacuole belongs in the plant cell as it requires more space and effort, while the smaller one fits into the animal cell.
Purpose of Cilia and where it can be found
Cilia is noodle like organelles that wave back and forth, able to catch the unwanted matter that lows inside a persons throat. It then gathers and gets ejected when a person coughs.
Single Celled organisms are called?
Unicellular, also called Prokaryotes.
Features of Prokaryotes
Single-Celled: Prokaryotes are unicellular organisms with a simple structure.
No Nucleus: Their DNA is free-floating in the cell, not enclosed in a nucleus.
Lack Membrane-Bound Organelles: They don’t have structures like mitochondria or a Golgi apparatus.
Types: Two main types – bacteria (common) and archaea (live in extreme environments).
Reproduction: They reproduce asexually through binary fission (splitting into two).
Important Roles: Help with decomposition, food production (e.g., yogurt), and in medicine.
What are multiple celled organisms called
Multicellular, also called Eukaryotes
Features of Eukaryotes
Complex Cells: Eukaryotes are unicellular or multicellular organisms with more complex structures.
Have a Nucleus: Their DNA is enclosed in a membrane-bound nucleus.
Membrane-Bound Organelles: They have organelles like mitochondria, Golgi apparatus, and endoplasmic reticulum.
Types: Can be unicellular (like Amoeba and Paramecium) or multicellular (like plants, animals, and fungi).
Reproduction: They reproduce sexually or asexually, through processes like mitosis or meiosis.
Important Roles: Eukaryotes make up the organisms we see around us, from plants and animals to fungi and protists.
