Description

What state of ploidy is the male gametophyte of a non-vascular plant? (Haploid) What state of ploidy is the seed of an angiosperm? (Diploid) What state of ploidy is the plant structure after fertilization occurs? (Diploid) What location of a plant holds the plant’s “stem cells”? (Apical meristem) List the different plant tissue present in vascular plant (Xylem and phloem) Define the xylem and phloem with respect to their function, composition, and the direction of flow. Xylem comprised of dead cells and concerned with the unidirectional movement of water and nutrients, Phloem comprised of living cells and concerned with sugar transport in all directions within a plant) Plant stomata are bordered by __guard__ cells Why is the inside of a leaf filled with gas? (transpiration for water as wells as CO2 for photosynthesis) What is the function of root hairs? (increase the surface area and reach of the root system for water and nutrients) The section of the plant where the leaves are attached to the stem is known as the (node) List 3 differences that exist between vascular and non-vascular plants (vascular plants possess a true root and shoot system, most vascular plants produce small gametophyte which grown on the sporophyte, most vascular plants do not require water for fertilization) What form of cell division results in the production of spores in non-vascular plants? (meiosis) List 2 difference that exist between a vascular seedless plant and a vascular seed producer. (Seedless plants require water for fertilization and produce larger gametophytes than seed producers) List 3 differences between angiosperms and gymnosperms (Angiosperms produce flowers, Angiosperms produce significantly fewer male gametophytes or pollen and angiosperms have evolved complex methods for pollination) What state of ploidy is the endosperm from seed of an angiosperm? (triploid) State 2 major differences between osmosis and diffusion. Diffusion does not always require a semipermeable membrane and diffusion is the motion of particles not specifically water) Differentiate between active and passive transport (Active transport requires energy typically in the form of ATP and moves particles against a concentration gradient while passive transport does not in both cases) Imagine you are studying how a plant root cell takes up phosphorus ions from the surrounding water. You discover that ATP is required for the cell to take up phosphorus. What type of transport do you think the plant is using? Are the phosphorus concentrations higher inside the root cell or in the

surrounding water? Justify your response. (active transport because the phosphorus is moving against its concentration gradient) Mention a stress hormone and explain the stressor and how the hormone impacts the plant (please...
