CELL REPRODUCTION DNA is the cell’s genetic material; chromosomes are the carriers of this genetic information. In proka-ryotes‚ the chromosome is a single circle of DNA. In eukaryotes‚ each chromosome is a complex of DNA and histone proteins found in the nucleus. BINARY FISSION Prokaryotic cells reproduce via binary fission. In this process‚ DNA Is replicated‚ and the cell splits in two roughly equal parts‚ each with a copy of the cell’s DNA. EUKARYOTIC CELL CYCLE Eukaryotic cells reproduce

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Plasma Membrane- surrounds an animal cell Cell Wall- surrounds a plant cell Mitochondria -"powerhouse" Prokaryotes vs. Eukaryotes Prokaryotes- most are single celled -lacks internal structures surrounded by membranes -DNA is concentrated in an area referred to as the nucleoid region -have cytoplasm -have plasma membrane Eukaryotes- single or mlti-cellular -contains membrane bound structures called organelles -more complex

Which of the following structures are present in both prokaryotic and eukaryotic cells? Both eukaryotes and prokaryotes have DNA as their genetic material‚ each also contains RNA. Both types of cells are covered by a cell membrane and are made of the same basic chemicals: proteins‚ fats‚ minerals‚ and carbohydrates. Ribosomes are responsible for the

yeast or small alga (Roberts‚ et. al. 2003). According to Guiffre‚ et. al. (2011)‚ a sensory apparatus allows the paramecium in detecting temperature‚ light‚ and a variety of attracting and repelling chemical substances. Their one complex cell‚ a eukaryote‚ conducts all of the organism ’s basic functions. It doesn ’t divide work between different tissues or cells like an animal. Instead‚ each Paramecium is capable of an aerobic exchange‚ similar to breathing‚ reproducing asexually by cell division

IntroductionThe concept of this lab is producing a replica of an animal cell‚ and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell and its contents also‚ to explore thedifferences between prokaryotes and eukaryotes. Cell theory states that all cells reproduce new cells‚while passing their genetic information. In addition‚ cells make up all living things‚ metabolize energyand that the chemical make-up of cells is similar. The objectives for this lab are to
