Plant Structures

Question 1

Plant Organs and Functions

Answer 1

Roots: absorbs water and minerals from the soil
Stems: transports mineral/nutrients around the plant
Leaves: get sunlight for photosynthesis
Flowers: Reproductive Organs
Fruit: reproduces reproductive cells and protects it
Cones: reproduces reproductive organs in non-flowery plants

Question 2

Physiological Processes:

Answer 2

• Photosynthesis: Process by which plants and other organisms use sunlight to create food from Carbon Dioxide and Water
• Cellular Respiration: process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
• Transpiration: process where plants absorb water through the roots and then give off water vapor through pores in their leaves
• Reproduction: process by which new individual organisms “offspring” are produced

Question 3

Plant tissues:

Answer 3

• Meristematic Tissue: Place where new cells are formed, causing the roots to become longer
• Ground Tissue: Water and Minerals move through the tissue into the center of the roots. Some of the food made during photosynthesis is stored here
• Dermal Tissue: The roots epidermis (outermost layer) perform the functions of protection and absorbtion
• Vascular Tissue: Transports food and water through the point

Question 4

Plant Structures:

Answer 4

• Cambium: cellular plant tissue from which pholem, xylem or cork grows by division
• Guard Cell: Special Cells around the Stomata that control their opening and closing
• Pholem: transports food and nutrients
• Seed: nourishment for the embryo, dispersal to a new location & dormancy during unfavorable conditions
• Stomata: Small opening in the epidermis that allows carbon dioxide, oxygen and water move in and out of the leaf
• Xylem: Transports Water
