Cell Unit Notes I. Life Processes - What makes something living? A. Biotic: Having life’s conditions Abiotic: Not having life’s conditions Homeostasis: The condition of maintaining a constant internal environment in living organisms. B. Characteristics of living Organisms (LIFE) 1. Nutrition - Food for energy and body (cell) repair and development 2. Transport - Move materials were needed in organism 3. Respiration - Able to generate energy for life processes

Chorus: Cells‚ cells they’re made of organelles Try to pull a fast one‚ the cytoplasm gels The nucleus takes over controllin’ everything The party don’t stop ’till the membrane blocks the scene Inside the vacuole we can float around for hours Running round with chloroplasts‚ lovin’ sunlight showers Cells‚ cells‚ they’re made of organelles First things first‚ there’s two different types- animal and plant cells that make up all life.

move the paramecium‚ it also pushes food into the “mouth” of the paramecium‚ where the food goes down a tube called the gullet to the protoplasm. There‚ the food is held in food vacuoles where they will be used and digested‚ and the nutrients will be distributed throughout the cell. The paramecium also has contractile vacuoles on both ends. These contractile values get rid of excess water that the paramecium absorbed through osmosis from its surroundings. Paramecium eat algae‚ bacteria‚ yeasts‚ and

Calculate the length of the vacuole. Answers 1) Calculate the magnification factor The line 5 (m is 20 mm long. So 20 000 (m = 5 (m Magnification is 20 000/5 = x 4 000. 2) Calculate the length of structure G Length of G is 12 mm = 12 000 (m Magnification

Structures and processes involved in the movement of substances into and out of cells. Epithelial cells – Epithelial cells are also referred to as eukaryotic cells. These types of cells have a unique nucleus and contain membrane-bounded organelles. Epithelial cells absorb and secrete‚ and the structures of a cells organelles can be viewed from an electron microscope. The nucleus – the nucleus of a cell contains most of the cell’s genetic material‚ organized as multiple long linear DNA molecules

contents. Its main function is to control what gets into and out of the cell. 4. Ribosomes - Ribosomes are where protein synthesis takes place. Some are attached to the rough endoplasmic reticulum‚ and some are free in the cytoplasm. 5. Lysosomes - Lysosomes are membrane-bound sacs of enzymes. In a controlled and specific way‚ they breakdown old or unneeded parts of the cell into small organic molecules that can be reused. 6. Mitochondria - Mitochondria are large organelles where oxygen is combined

There are a number of different ways the body protects itself against pathogens. Pathogens are microorganisms that cause disease. Such as harmful bacteria‚ viruses and fungi‚ many mechanisms occur in the human body to help keep it healthy and avoid any unknown pathogens from invading the body. The human body protects itself effectively against small bacterial and viral germs that can cause a disease‚ it is easy for pathogens to settle down and multiply due to the nutrients provided inside the human

other eukaryotic cells it additionally has a cell wall in since it has a much bigger central vacuole. They also have plasmodesmata‚ and chloroplast only found in plant cells. A nonphotosynthetic prokaryotic cell would differ from a generalized eukaryotic plant cell by the presence of a nucleus and the structures of the cell. Plants do not have bones structural strength besides the membrane‚ also the vacuoles contain nutrients and liquids and the chloroplasts contain the organelles that help the plant
