What is Muskgrass?
Plant Description
Chara is often called muskgrass or skunkweed because of its foul, musty almost garlic-like odor. Chara is a gray-green branched multicellular alga that is often confused with submerged flowering plants. … Chara has cylindrical, whorled branches with 6 to 16 branchlets around each node.
Why Chara is called Stone wort?
The algae Chara is called stonewort because its plant body is encrusted with calcium carbonate. Explanation: Chara is a genus of charophyte green algae in the family Characeae. It is a submerged aquatic freshwater algae.
How is green algae different from plants?
The structures between what are commonly known as aquatic plants and algae differ. Plants, unlike algae, have roots, stems, leaves, and a vascular system. … Green algae, such as sea lettuce, instead take in nutrients from the water column.
Which one of the following is wrong about Chara?
The globule is the male reproductive part and the nucule is the female reproductive part. The nucule or the oogonium lies above the globule or antheridium. Chara is a monoecious plant so it contains both male and female parts on a single plant. Hence, the right answer is option C.
Is Chara red algae?
Several major taxonomic groups are represented among aquatic plants, including nonvascular macroalgae (red algae, or Rhodophyta, e.g., Batrachospermum; green algae, or Chlorophyta, e.g., Chara and Nitella) and bryophytes (liverworts or Hepatophyta, e.g., Riccia; mosses, or Bryophyta, e.g., Fontinalis, Sphagnum).
Do Chara have flagella?
Male and female reproductive structures are found on the nodes, and the sperm have flagella. Although Chara looks superficially like some land plants, a major difference is that the stem has no supportive tissue. However, the Charales exhibit a number of traits that are significant for adaptation to land life.
Where is Chara found?

What fish is anchovy?
Anchovy are a small, silver fish, related to herring. They are a short-lived species, generally living for less than three years. They are found in large shoals, and feed on plankton and small fry (recently hatched fish larvae).
What is giant duckweed?
Giant duckweed is a native floating plant in Florida. Though very small, it is the largest of the duckweeds. Spirodela polyrhiza is frequently found growing in rivers, ponds, lakes, and sloughs from the peninsula west to the central panhandle of Florida (Wunderlin, 2003).
What eats the chara plant?
Chara is consumed by many species of ducks and provides habitat or shelter for invertebrates and small fish. … These invertebrates in turn are used as food by fish and other wildlife species (e.g., amphibians, reptiles, ducks, etc.).
Is Chara a plant?
Chara is a genus of charophyte green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures.
Which is called Stone Worts?
Chara plants are called stoneworts – stone plants. The ‘stony’ part of the plant consists of carbonate within the sort of arduous crystalline spar that impregnates cell walls.
What does Chara plant eat?
Grass carp will seldom control aquatic vegetation the first year they are stocked. They will readily consume Muskgrass. Grass carp stocking rates to control Muskgrass are usually in the range of 7 to 15 per surface acre.
What is Stonewort in biology?
Definition of stonewort
: any of various freshwater green algae (order Charales) that have a thallus differentiated into rhizoids and stems with whorls of branchlets and that are often encrusted with calcareous deposits.
What is difference between algae and fungi?

Is algae a plant or bacteria?
Algae are sometimes considered plants and sometimes considered “protists” (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).
Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch. … They are all specialized water plants.
Is Chara a Monoecious plant?
Monoecious (bisexual) plant of Chara shows occurrence of upper oogonium (female reproductive organ) and lower antheridium (male reproductive organ) on the same plant. … Reason: In Cucurbita, both male and female flowers are present on the same plant.
Are marchantia Monoecious or dioecious?

The stoneworts (e.g., Chara and Nitella) have long been important to plant research. These algae produce exceptionally large internodal cells that are uniquely valuable to various cellular studies. … Charophytes are now also becoming important organism in studies focused on stress-induced adaptations of plant cells.
