Gametes, or sex cells, are located in different parts of the body based on the individual's sex. In males, they are found in the testes, and in females, they are found in the ovaries. In plants, they are found within the reproductive structures.
Gametes are the sex cells that are located in different parts of the body depending on the sex of the individual. In males, sperm, which are the male gametes, are produced and stored in the testes. In females, eggs, or ovum, which are the female gametes, are produced in the ovaries. In terms of plants, gametes are found in the reproductive structures, such as flowers and cones. For instance, in flowering plants, the male gametes are located within the pollen grains produced by the anthers, and the female gametes are located within the ovule in the ovary of the flower.

Answer: True
Succession is the phenomena in which changes in the biotic and abiotic factors of the environment leads to change in the ecosystem. A succession is a process in which a biological community is replaced by another biological community until a mature ecosystem is formed this process is influence by environmental factors. Primary succession is the primitive environment where no biotic community previously existed it is followed by secondary and subsequent succession were life forms develop and form an ecosystem. Some of the environmental factors are:
Topographical : These are the change in the region or habitat were succession occurs. Landslides, volcanic eruption, glacier melting etc. are the examples , as these topographical changes can bring reformation of the landscape. The disturbance caused by these topographical changes will allow the disturbance tolerant species to repopulate the habitat. This can be a transition from primary to secondary succession.
Soil : It is an abiotic factor.The growth of the plants requires suitable soil conditions. The type of soil will affect which species will inhabit the area. The soil moisture and pH greatly affect the number of plant species in an area.
Climate : It can influence the direction of succession. Climatic factors includes rain, wind etc. For example a region lacking proper rainfall the species will be tolerant to dry and drought conditions. The region with heavy rainfall, the species will be more tolerant to moisture. Wind being a climatic factor can cause wind erosion affect the soil quality. Wind can lead to heavy forest fires can therefore, wiped out community.
Succession takes place when environmental factors affecting an ecosystem change. Therefore, the given statement is true.
Succession refers to the process of ecological change over time in a particular area or habitat. It involves the progressive and predictable sequence of changes in species composition and community structure, leading to the development of a stable and mature ecosystem.
It can occur in both terrestrial and aquatic ecosystems. It is typically categorized into two main types: primary succession and secondary succession. It is a dynamic process.

The right option is; B. Woody dicot stem
Woody dicot stem is a type of dicot stem that is made up of a cork, epidermis, cork cambium, xylem, phloem, cortex, vascular cambium, and pith. When woody dicots becomes mature, the vascular bundles connect together to form continuous rings along the interior of the stem. During winter in each year when there is reduced growth in plants that have woody dicot stems, there is production of annual rings which can be counted to determine the age of the plant.
