List the five characteristics all organisms on Earth share * The five characteristics all organisms share is: information‚ replication‚ evolution‚ cells‚ and energy (cerie) B. Explain why the first four are required for life * Cells allow things to go in and out of the organism (allows diffusion to happen so good things go in and bad things go out) * Energy is required because it

In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae. This was one of the first documented observations of positive aero taxis in bacteria. In 1882‚ he performed his

sustainable energy source? One process is photosynthesis. In plants‚ cells called chloroplasts collect energy from the sun and use water and carbon dioxide (photosynthesis) to make sugars.1 Light energy (called photons) hit single chlorophyll pigments in the cells of the plant leaves. 2 Photoautotrophs is the term used for plants that create energy out of sunlight. Plants that do not use the sun’s energy are called chemoautotrophs.3 For photosynthesis to begin a few conditions must be met; enough

are autotrophs. 4. What organelle allows plants (and plantlike protists) to photosynthesize? The chloroplasts allow plants and plantlike protists to photosynthesize. Objective: The goal of this lab is to identify and explore common features between organisms of the same kingdom. Theoretical Background: Plantlike Protists: - commonly referred to as algae - have organelles called chloroplasts

and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors are responsible for inherited traits such as purple flowers or round seeds in pea plants since Mendel experimented with garden peas. Mendel came up with a law known as Mendel’s Law of segregation. He tracked the inheritance of characters such as a flower’s color‚ which can occur as two alternative traits. When

other’s function to maintain their function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their specific function. The life processes of nutrition and respiration are related to photosynthesis and Aerobic Cellular Respiration. All organisms

Light Reaction (involves the sun) The roots suck up water from the ground‚ into the chloroplasts. In there‚ the water is sun-heated and gets split into hydrogen‚ oxygen and ATP. The oxygen then gets released for us to breath and the hydrogen is put to a different part of the leaf. Dark Reaction (doesn’t involve the sun) After the hydrogen

PLANT SYSTEMS QUESTION 1979:L. PETERSON/AP BIOLOGY In relation to plants‚ describe in detail one way of: a) measuring the rate of transpiration b) measuring the rate of photosynthesis c) separating pigments Essay : Transpiration is the loss of water vapor from land plants into the atmosphere‚ causing movement of water through the plant from the soil to the atmosphere via roots‚ shoot and leaves‚ which occurs mainly through the stomata. Factors which can affect the rate of transpiration are
