Transport
How do prokaryotes accomplish transport?
Through active or passive transport- channels in cell membrane
How do prokaryotes reproduce?
Binary Fission
What are the three key processes of development?
Growth, differentiation, and morphogenesis
Define osmoregulation
Balancing water and solutes (Na, K, Cl, glucose, proteins)
How do bacterial populations get genetic diversity?
Mutation, rapid replication, horizontal gene transfer
What is morphogenesis?
Construction of a 3D, multilayered structure- forms the overall body plan of specialized tissues, organs, and systems
What are the 5 main things that need to be transported?
Respiratory gases, nutrients, waste products, heat energy, information (such as hormones)
Provide + explain 3 examples on how plants disperse embryos
Examples include mammalian pollination, bee pollination, wind dispersal, fruit consumption, water dispersal
How is development controlled?
Genes, environment, and interactions between the two
How does a closed circulatory system work, and what organisms posses these?
Blood pumped from the heart is retained within a system of vessels that return blood to the heart.
Organisms include annelids and all vertebrates
Describe plant sexual reproduction
Plants alternate between a diploid (2n) sporophyte stage and haploid (n) gametophyte stage. The sporophyte produces spores via meiosis, which grow into gametophytes. The gametophytes then produce gametes through mitosis, which fuse to form a new sporophyte.
Differences in plant and animal morphogenesis
Animals: Lots of cell movement, deformation of epithelial sheets
Plants: No cell movement. Controlled direction of cell division instead.
What does the circulatory system look like in Mammals, birds, and crocodilians?
A four-chambered heart: separate ventricles for pumping to lungs and body, plus a complete separation of pulmonary and systemic cells.
Differentiate between ovoparity, ovoviviparity, and viviparity
Ovoparity: development occurs in eggs, outside of parent
Oviviparity: development occurs in eggs, inside of parent
Viviparity: development occurs inside of parent
Explain the process for each: protostome development and deuterostome development
Draw it on the board!
