Question

1. what process is occurring in the plants cells? transcription dna replication membrane transport photosynthesis

why?
experimental variables
what is measured during a controlled experiment?
when scientists set out to do an experiment, they first think about the variables that may affect the outcome of the experiment. a variable is any condition that may cause a change in the system being studied. some variables are measured quantitatively, like temperature, mass or height. other variables are measured in a qualitative manner, like color, texture or species. the most important factor is that only one variable is changed to ensure that the effect of only one variable can be measured.
model 1 - photosynthesis in an aquatic plant
the diagram in model 1 illustrates a clipping of an aquatic plant in water.

1. what process is occurring in the plants cells during in 1?
2. what gas is the plant using?
3. what source of energy is the plant using?
4. depending on the environment the plant is in, more or less gas may be produced. suggest a method for measuring the rate of gas production from the aquatic plant in model 1.
5. with your group, create a list of environmental factors that may affect the rate of gas production in an experiment. these factors could become variables in model 1.

Explanation:

Transcription is the process of copying DNA into RNA. DNA replication is the process of making an identical copy of DNA. Membrane transport involves the movement of substances across cell membranes. Photosynthesis is the process by which plants use light - energy to convert carbon dioxide and water into glucose and oxygen. In the presence of light as shown in the diagram, the process occurring in plant cells is photosynthesis.

Answer:

photosynthesis
