The world under the water( plankton, protists, flagelates
This organism can still catch its own food even in the absence of chlorophyll. Which organism is this?
The Euglena.
Ciliates can only catch their own food because........
They don't have chlorophyll.
Into how many parts are aquatic plants divided?
They are divided into 4 parts.
Why are these types of plants referred to as "submerged plants?"
Because they are are entirely (completely) under water.
Do emergent plants grow from a rhizome:
Yes, they do.
Why does the Euglena have a greenish colour appearance?
Because it has CHLOROPHYLL
Not having access to clean, safe and potable water might cause.....
CHOLERA.
What are aquatic plants collectively called?
They are collectively called HYDROPHYTES.
The Water Lily is an example of.............. plant
Floating plant.
State all the 7 characteristics of biotic organisms:
Movement, Respiration, Nutrition, Irritability (sensitivity), growth, Excretion, and reproduction.
What are Protists?
They are single-cell micro organisms in which flagellates and ciliates are members.
What happens to the paramecium when it is in trouble; there is unfavourable condition?
It loses its flagellum and forms a cyst.
Where are algae commonly found?
´They are commonly found in ponds, floating on the surface of the water .
Give an example of a floating plant with roots hanging in the water.
The Common Duckweed.
What is peculiar to wet meadows?
The colony of Common reed are surrounded by it.
What are planktons?
They are microscopic organisms are found floating close to surfaces of rivers and ponds
What are the 2 functions of the cilia in the paramecium?
´The cilia is used for obtaining food and to assist in movement.
Why is algae important to itself and some other protists under water?
Because they contain chlorophyll, produce oxygen for fish and micro-organisms
The Water Lily has a rhizome. What's a RHIZOME?
´It's a horizontal underground plant stem capable of producing the shoot and root systems of a new plant
Common reed and broad-leaf Cattail are example of...................plants.
Emergent.
What are the abiotic characteristics of an environment where living organisms live?
They include Temperature, water soil and weather
What does the paramecium look like?
It is Slipper-shaped, and has got
Parallel rows of hairlike cilia along the surfaces of the cells.
Why are algae simple plants
Mainly due to the absence ofabsence of stems and leaves. Some are microscopic, while others are filamentous, hair-like organisms. (Filamentous green algae).
What are the main characteristics of submerged plants?
´ They produce oxygen, provide shelter and food for animals like tadpoles and dragonfly larvae.
´
Expiain " Inflourescence"
´ They are a systematic arragements of flowers on a main branch/stem) with silky hairs.
