Ocean Geography
A process involving the movement of large plates on the earth's mantle.
What are plate tectonics?
The movement of molecules from an area of high concentration to an area of low concentration.
What is diffusion?
Three things most organisms need to survive.
What are water, oxygen, and food?
In the Kingdom Monera, these are prokaryotic, single-celled organisms that usually feed on dead organic matter?
What are bacteria (decomposers)?
True or False. The cell walls of brown algae have an important substance call algin that can be found in pudding, ice cream or salad dressing. Algin helps things stay mixed together. So does red algae (carrageenan). Algin or carrageenan in found in foods.
The process that creates new seafloor as plates move away from each other at the mid-ocean ridges.
What is seafloor spreading?
The simplest and smallest cell with no membrane-bounded organelles.
What are prokaryotic cells?
The process by which an organism uses the energy from the sun to produce its own food.
What is photosynthesis?
The making of organic material from inorganic substances using chemical energy
What is chemosynthesis?
Tiny floating organisms that are either small animals or protozoa.
What are zooplankton?
The four basic layers of the earth.
What are the inner core, the outer core, the mantle and the crust?
The diffusion of water across a selectively permeable membrane.
What is Osmosis?
The process by which a living organism takes energy from its surroundings and uses it to sustain itself, develop and grow.
What is metabolism?
Microscopic photosynthetic organisms that drift in the water.
What are phytoplankton?
Organisms that are made of long thread-like tubes filled with nuclei. They are considered multicellular organisms because they have no nuclei.
What are fungi?
The four major ocean basins.
What are the Pacific, Atlantic, Indian and Arctic Basins? (The Southern Basin is not a true basin)
In these cells that photosynthesize, (algae and plant cells) there are 2 special features: chloroplasts serving as sites for photosynthesis and a cell wall, providing shape and support.
What are eukaryotes?
Organisms that are able to produce their own food.
What are diatoms and dinoflagellates?
There are 45 species of these around the world, may restricted to the shallow water of the warm tropics. They have roots capable of extracting nutrients from the sediments in which they grow.
What are seagrasses?
Two geological differences between oceanic and continental crust.
What are density and composition?
Oceanic crust is denser and is composed of basalt, while continental crust is less dense and composed of granite.
The tendency of living organisms to control or regulate changes in their internal environment.
What is homeostasis?
The process by which food is converted into usable energy for life functions.
The seven major groups that living things can be divided (classified) into.
What are Kingdom, Phylum, Class, Order, Family, Genus, Species?
Found in the tropics and subtropics, these salt-tolerant plants get as big as shrubs or trees and can form dense forests along muddy shores.
What are mangroves?
