Apical meristem - Study guides, Class notes & Summaries

Agonist - Competitive inhibition, binds to active site and causes a signal response in receptive tissue. Antagonist (blocker) - Competitive inhibitor, binds to active site so signal molecules cannot bind but causes no response in receptive tissue, can bind and release eventually. Apply your understanding of channels and synapses to predict how various neurotoxins affect nervous function. - Neurotoxins block receptor proteins on the post-synaptic neuron. Example: tetrodotoxin form Fugu fish...

Meristem - correct answer Sites of rapid cell division in the shoot tips, root tips, and cambium. Apical meristem - correct answer Meristems located at the end of the shoot are called primary, or _________ meristems Scales - correct answer Buds are covered by _____________ that leave permanent scars on the twig when the buds break dormancy. These scars can be useful in tree ID. Apical dominance - correct answer The tendency for terminal buds to inhibit the growth of lateral buds is call...

"Hairy Flagellum" of Stramenopile - A flagellum with hair-like appendages; unique to the group Stramenopile. "Slug" - An aggregation of slime mold cells to essentially form a multicellular body. Absorption - A mode of nutrition in some Ciliates. Active transport - Energy-requiring process that moves material across a cell membrane against a concentration difference. Agar - Another material that makes up cell walls of Red Algae. Alginate - A material that makes up the cell wall of Brow...

charophytes - (aquatic) green algae land plants evolved from 3 key traits land plants share with charophytes - 1. rings of cellulose-synthesizing proteins embedded in plasma membrane 2. formation of a phragmoplast (helps form cell wall) 3. structure of flagellated sperm (not all will have this) adaptations enabling plants' move to land: why? - 1. CO2 2. sunlight 3. soil- nutrients 4. fewer predators/pathogens (never been seen before) adaptations enabling plants' move to land: problems...

Angiosperm dominant phase - sporophyte angiosperm phylum - Anthophyta Anther - the part of a stamen that contains the pollen. apical meristem - Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length. Are basidiospores haploid or diploid? - haploid Are spores haploid or diploid? - haploid Are sporophytes haploid or diploid? - diploid (2n) celery slide - crenate leaf margin - rounded teeth crustose - Dentate leaf margin ...

Parenchyma cells - Play a role in storage, secrection, and photosynthesis in cells. Have thin and flexible primary walls, large central vacuole, lack secondary walls, photosynthesize Ground Tissue - Tissue system that makes up the majority of a plant What is ground tissue composed of? - Parenchyma, collenchyma, sclerenchyma Collenchyma cells - Provide flexible and mechanical support; found in stems and leaves, used for new plants. Lacking secondary walls. Strings on a celery stalk Sclerenc...
