H Plants & Energy Vocabulary

Match the following

• Acid

• Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

• Turgor Pressure

• The pressure that water molecules in the central vacuole exert against the cell wall - allows plants to stand up

• pH Scale

• A substance that increases the hydrogen ion concentration of a solution

• ATP

• scale with values from 0 to 14, used to measure the concentration of H+ ions in a solution; a pH of 0 to 7 is acidic, a pH of 7 is neutral, and a pH of 7 to 14 is basic

• Cellular Respiration

• (adenosine triphosphate) main energy source that cells use for most of their work

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

Catalysts in photosynthesis

• Enzymes, pigment, and sunlight

• glucose and oxygen

• carbon dioxide and water

Reactants in photosynthesis

• Enzymes, pigment, and sunlight

• glucose and oxygen

• carbon dioxide and water

Products in photosynthesis

• Enzymes, pigment, and sunlight

• glucose and oxygen

• carbon dioxide and water

A cell that contains a nucleus and membrane-bound organelles is a ​ (a)   . A unicellular organism that lacks a nucleus and membrane-bound organelles is a ​ ​ (b)   .

• eukaryote
• prokaryote

A eukaryotic cell that contains a cell wall, chloroplast and a large vacuole is a ​ (a)   . A eukaryotic cell that does not have a cell wall or chloroplast and has small vacuoles is a ​ (b)   .

• plant cell
• animal cell

Match the following

• cell membrane

• site of protein synthesis in a cell, present in all cell types

• ribosome

• A rigid structure that surrounds the cell membrane and provides support to plant cells

• mitochondria

• Takes up a large portion of plant cell interior, filled with water, allows for turgor pressure

• central vacuole

• thin, flexible phospholipid barrier around a cell; regulates what enters and leaves the cell

• cell wall

• Organelle that is the site of ATP (energy) production

Match the following

• stroma

• Green pigment in plants, algae, and other photosynthetic organisms that absorbs light energy used to carry out photosynthesis

• chlorophyll

• organelle found in cells of plants that captures the energy from sunlight and converts it into chemical energy

• thylakoid

• fluid portion of the chloroplast; outside of the thylakoids, location of Light Independent Reactions

• chloroplast

• A flattened membrane sac inside the chloroplast that hold the pigment chlolophyll, Location of Light Dependent Reactions

Primary component of plant cell walls
