Cells Flashcards
Learn about cells organelles and so on.... (30 cards)
What is in a PLANT cell?😄👌
There is a cell membrane,cell wall,cytoplasm,nucleus,A LARGE PERMANENT vacuole,chloroplasts,and mitochondria
What is a ribosome ?😃
A ribosome is a tiny organelle where protein synthesis occurs(where protein is produced)
Name what a nucleus is and its function?🙈
A nucleus contains genetic material,including DNA which control the cell’s activities.
Name a function of cytoplasm and why we need it?🙃
Cytoplasm is a jelly like material which contains dissolved nutrients,salts and structures.THESE ARE CALLED ORGANELLES.This is also where most chemical reactions happen.
What is a mitochondria?🤪
Mitochondria are organelles that contain enzymes for respiration, and where most energy is released in respiration
Define a Cell Membrane and what it does?😑
Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell
Plant cells have large permanent vacuole which contain what and How is it used?😲
These vacoules are contained with cell sap made from sugars like glucose which help keep the cell Turgid.(swollen or weird shape/to keep its shape)
How is a chloroplast involved in photosynthesis?
🙋♂️
Chloroplasts are organelles that contain a green pigment called chlorophyll which absorbs light energy for photosynthesis. They contain the enzymes needed for photosynthesis.
What is a cell wall created from and how does it help the plant cell?😉
The cell wall is made from cellulose fibres and strengthen the cell and supports the plant.
Animal cells may have vacuoles too. How is this different from plant ones?💪
Animal cells may have SMALL TEMPORARY CELLS while plants have large permanent vacuoles.
An animal’s vacuole is commonly used to store or transport substances
What are in an ANIMAL cell?🤔
Nucleus, cell membrane, cytoplasm,mitochondria
What are ENZYMES?😉
Enzymes are biological catalysts that speed up the rate of a reaction.
What is a Eukaryotic cell?😐
Eukaryotic cells are cells that contain a nucleus
What are prokaryotic cells?🤨
Prokaryotic cells are cells without a nucleus.
The nucleus contains __________ which are designed into 23 pairs and also include DNA. Fill in the missing word.
Chromosomes
What is the definition for respiration?🤴
Respiration is a reaction which takes place in every cell of our body and it produces energy.
What does DNA stand for?😅
Deoxyribonucleic acid
In a plant cell, the cell wall _________ the cell membrane. What is the missing word?👊
Protects
What might mitochondria be known as?😏
The powerhouse of the cell.
A Bacterium is a what type of cell?👋
Prokaryotic cell
What do prokaryotic cells contain?💥
Cell wall, cell membrane, plasmids ,loops of DNA
What is the average size of a Eukaryotic cell?
Between 5 - 100 micro metres
What layers do a Eukaryotic cell have?🧐
A cell membrane which is covered by a cell wall and FUNGI.
DNA can be found in a nucleus located in a Eukaryotic cell but other type of DNA can be seen in simple Eukaryotic organisms?😇
Plasmids
