What is the meaning of juvenile stage?
Juvenile: A life history stage of growth and development of some mammals that occurs between the end of infancy and the onset of adulthood. In the apes and other primate species, puberty and reproduction may begin before the end of their juvenile stage.
How is juvenile phase different from vegetative phase?
Answer: => The juvenile phase: All organism has to attain a certain stage of growth and maturity before the can reproduce. This is called juvenile phase. The vegetative phase: the period of growth or the period before reproductive phase in plants is termed as vegetative phase.
What is a juvenile plant called?
The vegetative phase is sometimes referred to as the juvenile phase, which is a period of time when plants are not capable of flowering. Plants started by seed have a juvenile phase and they must develop to a certain maturity before they attain the capacity to flower.
What marks the end of juvenile phase in flowering plants?
The end of the Juvenile phase or Vegetative phase in flowering plants is marked by the beginning of Reproductive phase and reproductive phase can be seen easily in the plants when they come to flower.
What do juvenile fish eat?
Early stage larvae swim poorly, but later stage larvae swim better and cease to be planktonic as they grow into juveniles. Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by larger animals.
How is the juvenile phase different from the reproductive face?
Juvenile phase is the period of growth between the birth of an organism and before its reproductive maturity. The reproductive phase is the period of growth after juvenile phase when an individual attain reproductive maturity and reproduces.
What do you know about juvenile phase?
A) Juvenile Phase : This phase is the growth phase.In an individual organism juvenile phase is considered as the growth period that happens after the birth and before the organism meets the reproductive maturity. The reproduce and give birth to offspring.
What is the juvenile phase in plants?
Does Mango show inter flowering period?
Interflowering period is the period of time in between two successive flowering in a plant. So it is always absent in monocarpic plants. In given list rice, wheat and marigold are monocarpic , they lack interflowering period whereas mango and apple are polycarpic , they have interflowering period.
Why is an apple called a false fruit?
False fruits develop from other floral parts except the ovary. > Some false fruit is Parthenocarpic i.e. do not contain seeds. Apple develops from the thalamus, that is why it is referred to as false fruit.
What are the advantages and disadvantages of trying a juvenile as an adult?
Several advantages and disadvantages of juveniles being tried as adults must be reviewed in each case to determine if a waiver into adult court is the best option. 1. It eliminates the juvenile threshold for consequences associated with severe crime.
What happens when a juvenility plant becomes an adult?
Once mature, the adult condition is highly stable, and reversion to the juvenile state is rare. The transition from juvenile to adult may also be associated with changes in leaf shape and thickness, pigmentation, thorniness, and rooting ability. However, these changes are often less distinct in herbaceous plants than in woody species.
How long does juvenility last in a tree?
Juvenility in most trees is a significant impediment in breeding programs. For example, apple seedlings usually remain vegetative for 7–9 years after seed germination (Flachowsky et al., 2009), while olive seedlings remain juvenile for 4–5 years (Moreno-Alias et al., 2010).
Is the retention of leaves a characteristic of juvenility?
Leaf retention is also a characteristic of juvenility. It can be significant in species such as beech (see Figure 11.5), where the phenomenon is exaggerated, and the trees The juvenile stage is a period after germination that is capable of rapid vegetative growth and is unlikely to flower.
