C4: Plants/Animals Flashcards
(128 cards)
angiosperms
A vascular, seeded plant that also has flowers
coelomate
When an animal develops a body cavity within the mesoderm. This allows for more specialized organs and structures
ectothermic
- what kind of animals are ectothermic?
A cold blooded creature that does not produce enough metabolic heat to control body temperature. They rely on external or environmental heat sources
- fish, amphibians, reptiles, invertebrates
gametophyte
One form of an organism that performs alternation of generations. A multicellular, haploid organism that develops from a haploid spore, and produces haploid gametes (male, female or both) via mitosis. This is the dominant form of non-vascular plants
gymnosperms
A vascular, seeded plant that does not have flowers. Most are cone-bearing
homeothermic
Warm blooded organisms with a constant body temperature
ingestive feeders
An organisms that ingests food, then digests it inside their body or cell
metanephridia
- what kind of organisms have this?
Excretory tubules that have ciliated funnels and remove waste from the blood and fluid. These tubules lead to exterior pores where wastes are discharged. Also known as nephridia
- mollusks, annelida, arthropods
metazoa
A subkingdom of animals that have tissues
mutualism
A symbiotic relationship where both species benefit
- hemolymph
- hemocyanin
- hemocytes
- interstitial fluid that bathes organs and tissues, there is no difference between hemolymph and blood
- primary oxygen transporter molecule in hemolymph
- free floating cells that function in immune protection
open circulation
- what kind of organisms have this type of circulation?
Where there is no difference between blood and interstitial fluid. Hemolymph bathes tissues, and is composed of water, inorganic salts and organic compounds. Hemocyanin is the primary oxygen transport molecule. Free-floating hemocytes perform immune protection
- mollusks, arthropods
parazoa
A subkingdom of animals with no tissues, no symmetry, no body cavity, and no segmentation
phloem
One of the vascular systems in plants, used to transport nutrients (such as sucrose) from source to sink. It is composed of sieve and companion cells
how do sieve cells and companion cells interact?
companion cells are attached to sieve cells by plasmodesmata; sieve cells transport nutrients while companion cells support them
root cap
the end of each root
apical meristem
where cell division occurs in plants to keep the root cap forward
nodes
where leaves attach to stems
cuticle
waxy substance that covers the layers of cells in a plant to prevent water loss
stomata
holes or pores in leaves that allow exchange with air
psuedocoelomate
- what kind of organisms are psuedocoelomate?
Animals that have a body cavity that develops between the endoderm and mesoderm
- nematoda
radial symmetry
- what kind of organisms have this kind of symmetry?
When an organism resembles a pie, where several cutting planes produce roughly identical pieces. Such an organism exhibits no left or right sides, but have a top and a
bottom (dorsal and ventral surface)
- cnidaria
water vascular system
- what kind of organisms have this kind of system?
A hydraulic or fluid system used for locomotion, food and waste transportation and respiration. Canals connect numerous tube feet. The system moves by alternately contracting muscles that force water into the tube feet, causing them to extend and push against the ground, then relaxing to allow the feet to retract. This allows movement that is powerful, but very slow
- echinoderms
xylem
One of the vascular systems in plants, used to transport water from roots to leaves. It is composed of parenchyma cells, tracheids and vessel elements
