Cells

=Cells= = = 1) A cell is a basic unit of life. 2)Cells consists of a mass of matter called protoplasm, which is made up of 70 to 90% water and the rest is made up of mineral salts and organic compounds such as carbohydrates, fats and proteins. 3)Cells are of different shapes,sizes,structures and types. 4) All living things are made up of cells. 5) An animal cell contains cell membrane, cytoplasm and nucleus. 6)A plant cell contains cell wall,cell membrane,cytoplasm,chloroplasts and nucleus. 7)A plant cell consists of rough ER(endoplasmic reticulum), smooth ER(no ribosomes) , necleus, nucleolus, cell membrane(plasma) , vacuole, mitochondrion, cytoplasm, chloroplast, cell wall, Golgi apparatus. (More Difficult) 8)An animal cell consists of nucleus, nucleolus, mitochondrion, Iysosome, Golgi vesicles, Golgi apparatus, vacuole, rough ER(endoplasmic reticulum) , smooth ER(no ribosomes) , centrioles, cytoplasm, cell membrane(plasma). (More Difficult) 9) The cell membrane allows materials to pass through the cell. 10) Cell is the smallest unit of life. 11) The nucleus controls all the activites in the cell. 12)The chloroplasts of the plant cell contains a green pigment call chlorophyll. 13)The nucleus contains information that can be passed down from one generation to another. 14) The plant has chloropast but the animal cell does not as it cannot make its own food. 15)Yeasts have one cell. 16)There are millions of different types of cells. 17)There are cells that are organisms onto themselves, such as microscopic amoeba and bacteria cells. 18)And there are cells that only function when part of a larger organism, such as the cells that make up your body. 19)The cell is the smallest unit of life in our bodies. 20)In the body, there are brain cells, skin cells, liver cells, stomach cells, and the list goes on. 21)All of these cells have unique functions and features. 22)And all have some recognizable similarities. 23)All cells have a 'skin', called the **plasma membrane**, protecting it from the outside environment. 24)The cell membrane regulates the movement of water, nutrients and wastes into and out of the cell. 25)Inside of the cell membrane are the working parts of the cell. 26)At the center of the cell is the cell **nucleus**. 27)The cell nucleus contains the cell's [|DNA], the genetic code that coordinates protein synthesis. 28) The cell is a basic structural unit of all known living organisms. 29) An animal cell does not have a cell wall. 30) We humans have an estimated number of 100,000,000,000,000 cells. 31)The nuleus is the most obvious organelle in any eukaryotic cell. 32The nucleus of the cell stores infomation passed down from generation to another 33)There are single-celled organisms and multi-celled organisms 34)Cells were found out from a cork 35)There are about 95% of all the cell in the body are bacteria. 36)Each cell stores its own set of instructions. 37)Amoeba and bacteria are single-celled-organisms 38)There are two types of cells: eukaryotic and prokaryotic. Prokaryotic cells are usually independent, while eukaryotic cells are often found in multicellular organisms. 39)The word cell comes from the Latin cellula, meaning "a small room". 40)The cell was discovered by Robert Hooke in 1665. 41)The cell is the basic structural and functional unit of all known living organisms 42) Cells are too small to be seen without magnification. 43)Eukaryotic and prokaryotic cells are two main types of cell. 44)We will grow taller and bigger because the number of cells in our body will increase. 45)Plant cells have vaccuoles which consists of water. 46)There are more than two hundred types of cells in our body. 47) The longest cell in our body is the neuron cell,which is located in the spinal cord,near the central nervous system. 48) Cells hane varying life spans. 49) Cells cannot be seen with a naked eye. 50) Different types of cells reproduce through different methods. 51) Plant cells have a regular shape and animal cells does not have a regular shape. 52)DNA stands for deoxyribonucleic acid. 53)Some cells reproduce by splitting itself. 55)Plants can make food as they have chorophyll in thier chloroplast 56)Cells come in differentiated shapes,sizes and structure to help suit their specialized functions.
